Britain's most famous milk chocolate maker has decided to warn milk chocolate lovers that Britain's most famous milk chocolate contains - milk.

The latest Cadbury Dairy Milk wrappers feature a logo showing a glass and a half of milk being poured into a chocolate chunk, put milk first in a list of ingredients and explains that there is "The equivalent of three quarters of a pint of milk of fresh liquid milk in every half pound of milk chocolate".

But Cadbury says it is also necessary to print warnings in capital letters in yellow boxes saying "CONTAINS: MILK" in case people who are allergic to milk do not realise that there is milk in Cadbury Dairy Milk bars.
